Some candidates would be helped

Given that both the left-wing and right-wing voter bases are fired up, Trump and Obama share the problem of inadvertently fanning the flames of the wrong voter base while on the campaign trail.

While the Repblican candidates face the tough decision of whether to strongly identify with Trump, the Democratic candidates face the simpler problem of determining whether it is wise to invite Obama to campaign for them, without regard to any need to strongly identify with Obama.

In the end, Obama will only be of substantial benefit for some of the Democratic candidates, and he should carefully identify who those right candidates are.
